This bug releated to Web Extensions in Safari 14. When I try to open a window with browser.windows.create (or include an iframe on page) pointing to my index.html and inside of it I make an API requests to host (https) that explicitly specified in permissions manifest field, the cookies are not send to this host. So in other words I can't do API requests to my own server from such windows. This works only from browser_action popover. This behaviour differs from all other browsers, they allow to do this.
